Logging in from another device does not allow access to Secret Chats. When a message is deleted on one side of the conversation, it gets also deleted on the other side. In a Secret Chat, messages are never stored in the Telegram cloud but are only kept on the users’ mobile phones.
They are protected with end-to-end encryption and are device-specific. For users who seek a higher level of security and privacy, Telegram has its Secret Chat option. Telegram explains this setup as necessary to enable restoration of chat history for Cloud Chats. End-to-end encryption is used in so-called Secret Chats, which are protected in a stronger way. The client-server /server-client encryption layer is the standard method applied to all chats that are referred to as Cloud Chats. Telegram uses two layers of encryption: client-server / server-client encryption and end-to-end encryption. MTProto performs on a satisfactory level in such situations.
This protocol was chosen as a solution to the problem of sending large files over weak connections. Telegram uses MTProto, a protocol developed specially for use in this network. Particularly, Telegram secures messaging in its network using the following mechanisms: Telegram implements quite a number of security measures and mechanisms that it explains in its FAQ. So, is Telegram secure? Telegram’s security concept Still, Telegram remains an IM app of choice for millions of users, and every day, more people consider adopting it for themselves. On the other hand, Telegram has not been immune to cyber attacks, one of which occurred in 2020 and resulted in a leak of personal data of millions of Telegram users. On the one hand, Telegram has been around since 2013 when it was founded by Pavel Durov and his brother, Nikolai Durov, and in 2021, has reached as many as 500 million active users. Telegram messenger, an instant messaging app, can raise such concerns, too. After notorious security breaches in Facebook, LinkedIn, Yahoo, and many other applications, where massive amounts of user data got exposed, we tend to think twice before trusting our data to social media. Is it secure? We ask this question whenever we are going to access any social network, messenger, online store, or virtually any app where we need to provide personal data.
